In the figure above, what is the length of segment PQ ?
I. S is the midpoint of segment RT
II. Segment PT has length 10 and segment QT has length 6.
Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient to answer the question asked.
Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient to answer the question asked.
BOTH statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
EACH statement ALONE is sufficient to answer the question asked.
Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.
Option B is the correct answer.
Length of line segment PQ?
Statement I is insufficient: From this, we only infer that RS = ST. Nothing about PQ. So not sufficient.
Statement II is sufficient:
If PT = 10 and QT = 6
Then PQ = 4
